LS1021AQDS has a variant with DDR4 slot. This patch adds a new defconfig
for this variant to enable DDR4 support. RAW timing parameters are not
added for DDR4. The board timing parameters are only tuned for single-
rank 1600 and 1800MT/s with Micron DIMM 9ASF51272AZ-2G1A1 due to DIMM
availability.

Spin table is at the very beginning of boot code. Each core has an individual
release address within the spin table, the ft_cpu_setup fn updates the
"cpu-release-addr" property of each cpu node with the corresponding release
address.
Also fix CPU_RELEASE_ADDR to point to secondary_boot_func.

Since commit ddaf5c8f3030050fcd356a1e49e3ee8f8f52c6d4
(patman: RunPipe() should not pipe stdout/stderr unless asked),
Patman spits lots of "Invalid MAINTAINERS address: '-'"
error messages for patches with global changes.
It takes too long for Patman to process them.
Anyway, "M: -" does not carry any important information.
Rather, it is just like a place holder in case of assigning
a new board maintainer. Let's comment out.
This commit can be reproduced by the following command:
find . -name MAINTAINERS | xargs sed -i -e '/^M:[[:blank:]]*-$/s/^/#/'

The "S: Orphan" in MAINTAINERS means that the maintainer in the
"M:" field is unreachable (i.e. the email address is not working).
(Refer to the definition of "Orphan" adopted in U-Boot
in the log of commit 31f1b654b2f395b69faa5d0d3c1eb0803923bd3b,
"boards.cfg: move boards with invalid emails to Orphan")
For patch files adding global changes, scripts/get_maintainer.pl
adds bunch of such invalid email addresses, which results in
tons of annoying bounce emails.
This commit can be reproduced by the following command:
find . -name MAINTAINERS | xargs sed -i -e '
/^M:[[:blank:]]/ {
N
/S:[[:blank:]]Orphan/s/^/#/
}

Each CPU of PowerPC has its default linker script under the CPU
directory, except mpc8xx.
Every mpc8xx board has its own linker script under the board
directory, resulting in lots of duplication of linker scripts.
I notice eight mpc8xx boards have the same linker script.
We can decrease the number of linker scripts by putting a single
default linker script, arch/powerpc/cpu/mpc8xx/u-boot.lds.

T1042RDB is a Freescale reference board that hosts the T1042 SoC
(and variants). The board is similar to T1040RDB, T1042 is a reduced
personality of T1040 SoC without Integrated 8-port Gigabit(L2 Switch).
T1042RDB is configured with serdes protocol 0x86 which can support
following interfaces
- 2 RGMII's on DTSEC4, DTSEC5
- 1 SGMII on DTSEC3
DTSEC1, DTSEC2 are not connected on board.
This Patch
- add T1042RDB support
- updates README file for T1042RDB details and update commands for switching
to alternate banks from vBank0 to vBank4 and vice versa
This patch also does minor clean ups for fdt defines for T1042RDB and
T1042RDB_PI board

LS2085a has 2 regions in system memory map. Region1 is default map from
where system boots. Once u-boot is moved to DDR, IFC is re-mapped to
Region2.
So, update gd->env_addr to reflect correct address.

MXC SPI driver has a feature whereas a GPIO line can be used to force CS high
across multiple transactions. This is set up by embedding the GPIO information
in the CS value:
cs = (cs | gpio << 8)
This merge of cs and gpio data into one value breaks the sf probe command:
if the use of gpio is required, invoking "sf probe <cs>" will not work, because
the CS argument doesn't have the GPIO information in it. Instead, the user must
use "sf probe <cs | gpio << 8>". For example, if bank 2 gpio 30 is used to force
cs high on cs 0, bus 0, then instead of typing "sf probe 0" the user now must
type "sf probe 15872".
This is inconsistent with the description of the sf probe command, and forces
the user to be aware of implementaiton details.
Fix this by introducing a new board function: board_spi_cs_gpio(), which will
accept a naked CS value, and provide the driver with the relevant GPIO, if one
is necessary.

where logic has been added to identify whether or not the previous
reset was a PORz. PLL initialization is skipped in the case of a

This is an implementation of GPIOs for Tegra that uses driver model. It has
been tested on trimslice and also using the new iotrace feature.
The implementation uses a top-level GPIO device (which has no actual GPIOS).
Under this all the banks are created as separate GPIO devices.
The GPIOs are named as per the Tegra datasheet/header files: A0..A7, B0..B7,
..., Z0..Z7, AA0..AA7, etc.
Since driver model is not yet available before relocation, or in SPL, a
special function is provided for seaboard's SPL code.

The IMX6 MMDC calibration registers depend on propagation delay and capacitive
loading between the SoC's MMDC and the DDR3 chips. On the Ventana boards the
board layout varies little in trace-lengths such that propagation delays are
irrelevant thus we can simply things by using calibration values obtained
from various board layouts based on a common SoC and DDR chip configuration.
This eliminates board-model from being needed allowing more flexibility. These
values were tested on a large sample size of Gateworks Ventana boards ranging
in layout, and memory configuration over the entire temperature range supported.
